Quote - Blender, add grid, select outer edges of grid, Transform To_Sphere=1.  Blender has a tool/function to do everything in the OP's tut.

Thanks for posting!  That's good info to know, and I'm relieved to know for sure that the particular operation is something that can be done easily in other apps as well.  I didn't wanna post an application-specific tutorial in this forum.
